Paper 5
Subjective Part of MY Paper Held on 14 December

In Control Flow what is the XON and XOF?

Ans: In control flow XON indicates the start of communication and XOFF indicates temporary pause in communication if XON then it returns True and If XOFF then it returns False

What is Real Time clock?
Ans:
Real Time Clock is a device which updates time even the system is off /computer is shutdown.

What do you understand by Self test mode of UART what happens in this situation?
Ans:
When UART is in self test mode then output becomes input output of UART rounds to input so we can receive what we send.

What is the function of Interrupt ID Register?
Ans:
Ans: It is used to find the cause of interrupt

A Table was given with irregular options 5 Marks
Ans:
IRQ7 = Printers
NMI = Low Priority
IAH = Real Time Clock get/set Time
8087 = Interrupt Driven
Keyboard = Int 9

Which one is better Serial or parallel communication?
Ans: Cost is reduced in serial communication but transfer rate is low so parallel communication is better because it is faster than serial in terms of speed and it is valuable for short distances only


Paper 6

MCQs kitny ta 20 k 16??????

konsy lectures sy Question a rhy ha

Past papers ma sy MCQ a rha ha k ni...???

Plz tell me any body....

MCQs new or from OLD Papers ???

Thanks Fairy

if ((( inport((*lpt) +1)) & 0x80) == 0x80)

5-Marks

draw/describe status register A of RTC?

How can we enable the 0x0f to perform interrupt driven I/O? and how PIC will handle this interrupt?

MCQs mosly from old papers

Remember me in Your Prayers....Thanks

Most MCQS from Past Papers:

Some of them were about:
BIOS support --- Uart are com ports.
To distinguish 486 Pentium CPUID is used?
low nibble
Bios data area in memory start at address---
Number of hardware interrupts in IVT---
Device which requires timing signal..

Subjective:

COM1, COM2 IRQ Interrupt ?? (2)
Purpose of IBF & OBF in Port 64H (2)
Binary value of LED status byte (3)
Draw/write Clock status Register B (5)
Steps involved for loading divisor UART (Un-understandable Q) (5)
